LSS10020T
Enhanced IO Expansion
LSS10021 is an enhanced IO expansion chip with 8-channel IO expansion functionality.
This chip features an ultra-low operating current of 0.5 uA and includes 8 IO channels that can be configured as either inputs or outputs. It supports both analog and digital signals, and the output can be set to PWM mode. The duty cycle and frequency can be configured through registers.
We adjust the parameters to customer’s specific-needs.
